Get check-mirrors able to download in tmpfs
When running on lizard, check_mirrors.rb does some I/O we could and should easily avoid by downloading the iso images in a tmpfs.
For that, we can hack around in puppet, but the easiest and most standard way would be that check_mirrors.rb sets TMPDIR to ENV[‘TMPDIR’] if the last one is set, rather than only assuming doing all its work in PWD.
But then, that would mean also adapt the —keep option so that it copies the downloads where they belong.
